Plumbing Installation
Refer to the tubing assembly instructions in
schematic/flow diagram on
Feed Water Connections
Connect tubing to the Feed water inlet. Observe the following:
1.
To minimize pressure loss, the tubing size should be at least 1/2".
2.
Install an optional pressure gauge (part number D1006272) before the pre-filter. This allows you to measure the
pressure differential across the filter cartridge.
3.
Install a tee, with a shutoff valve on the branch, to provide a connection for introducing cleaning solutions.
4.
If necessary, install a pressure regulator (50 psi downstream max. setting) in the inlet plumbing, to assure con-
stant pressure and to prevent harmonic vibration.
5.
Install a shutoff valve in the inlet plumbing to simplify maintenance and service.
6.
If the feed water can be used for a short period, install bypass plumbing around the unit.
Concentrate Water Connections
1.
Direct 3/8" piping to drain from the outlet of the unit.
2.
To prevent siphoning of the water in the unit to drain, raise the concentrate piping above the level of the mod-
ules and provide an anti-siphon loop.
WARNING! An air gap must be provided between the end of the concentrate tubing and the drain
to prevent back-siphoning of drain contents.
Product Water Connections
The product water exits the unit at the top of the module housings. Connect the product tubing as shown in
page 12
through
Figure 15 on page
CAUTION!
This unit produces high quality product water. This water can be contaminated by
plumbing following the unit or it can corrode the plumbing. Use only plumbing compo-
nents of inert material that are compatible with the application.
The connection of the main product tubing to service plumbing will depend on how the product water will be stored.
CAUTION!
Reverse osmosis elements will fail immediately if pressurized product water is allowed
to flow backward into the unit.
